Just took my intake off to check for a suspected vaccum leak at the #5 runner and found a cam lobe starting to go (flat tappet), along with the suspected gasket issue.I do not the actual airflow of my heads (DOOE-R)but they were done by Engine Systems for a blown injected 572" mudrunner back in the late 80's early 90's before we had the options available that we now have. The intake is a weiand hi-ram with bird catcher that is extensively ported that came with the heads and was also ported by Engine Systems.The heads/intake are going back onto a 501 that should be around 13.5:1 compression.Car is less than 2800 lbs with me in it and will be track only 1/4 mile, 4:56 gear, C-6 trans and 9" converter.If any vendors would like to p.m. me a price with "approximate" specs please do so.Thanks, Sheldon

Sheldon,There are several folks on here that will hook you up with a good cam.Since Ted at Engine Systems did lots of the work, it may also be a good idea to give him a call for his input.You can get him at (770) 491-0653.ThanksKeith
